Transfer case help

Hi guys im new here but have been lurking around for a little while now. I've got two questions for you guys. My truck is a 1979 F150 4x4 http://i69.photobucket.com/albums/i5.../79F150032.jpg. I purchased the truck fairly recently and have been doing a little tinkering with it. After searching this site and countless other forums I thought I had figured out what transfer case I had. However, my shift pattern doesn't match up with a NP203 so I guess it might just be easier to post a pic and get some help. http://i69.photobucket.com/albums/i5.../79F150015.jpg

Also while trying to figure out the pattern and dealing with this darn B&M shifter I screwed up my linkage or something in the transmission. I removed the B&M and tried to move linkage by hand but nothing. Got under truck and tapped on linkage, nothing. Any help would greatly be apperciated.

There should be a tag under all that gunk that tells you what it is. If it is cast iron then it is a NP205 (kinda looks like a 205 to me but its hard to tell in the pic) aluminum would be a 203.

sorry for the poor pics. I found the tag and cleaned it but due to the location I cannot read what it says. I thought it was a 203 based on the it not having a drain plug and being so large. However, the shift pattern seems like an H pattern with neutral in the middle:

4low 2low
n
4hi 2hi

that case is not a 203 the 203 is a fulltime 4 wheel drive case. and that shift pattern doesnt look like a 205 but in 79 you either got a 203 or 205. and in my experience i've never seen a case that has a 2low option.

Are you talking about never seen a Ford transfer case with 2 lo or never seen one period? I had a 78 RamCharger 440 that had 2 lo, patter was:
4lo
2lo
N
2hi
4hi

Seems like my neighbors 79 Bronco has the same thing. I'll have to look again.

I've personally never seen one in a ford. your neibours bronco won't have 2low either because it was either a part time 205 or the fulltime 203. For never offered any other cases in those year of truck
